Ants in a labyrinth: A statistical mechanics approach to the division of labour (2011)
Journal Article

Division of labour (DoL) is a fundamental organisational principle in human societies, within virtual and robotic swarms and at all levels of biological organisation. DoL reaches a pinnacle in the insect societies where the most widely used model is... Read More about Ants in a labyrinth: A statistical mechanics approach to the division of labour.

Group dynamics and record signals in the ant Temnothorax albipennis (2011)
Journal Article

Many purely physical complex systems, in which there are both stochasticity and local interactions between the components, exhibit record dynamics. The temporal statistics of record dynamics is a Poisson process operating on a logarithmic rather than... Read More about Group dynamics and record signals in the ant Temnothorax albipennis.

Outcomes from stimulation of the caudal zona incerta and pedunculopontine nucleus in patients with Parkinson's disease (2011)
Journal Article

Introduction. Axial symptoms including postural instability, falls and failure of gait initiation are some of the most disabling motor symptoms of Parkinson's disease (PD). We performed bilateral deep brain stimulation (DBS) of the pedunculopontine n...

Blinkered teaching: Tandem running by visually impaired ants (2011)
Journal Article

During tandem runs, one ant worker recruits another to an important resource. Here, we begin to investigate how dependent are tandem leaders and followers on visual cues by painting over their compound eyes to impair their vision. There are two ways...

Time-course of attentional bias for threat-related cues in patients with chronic daily headache-tension type: Evidence for the role of anger (2011)
Journal Article

This study investigated the role of anger in attentional bias for linguistic threat-related stimuli in individuals with chronic daily headache (CDH) tension type and healthy controls. Attentional bias was assessed using a visual probe task which pres...

A quantitative comparison of psychological and emotional health measures in 360 plastic surgery candidates: Is there a difference between aesthetic and reconstructive patients? (2010)
Journal Article

This study examines the utility of the aesthetic and reconstructive categorization for making treatment decisions in patients seeking facial surgery. A total of 360 patients with aesthetic or combined functional aesthetic deficits were included. Vali...

Ant search strategies after interrupted tandem runs (2010)
Journal Article

Tandem runs are a form of recruitment in ants. During a tandem run, a single leader teaches one follower the route to important resources such as sources of food or better nest sites. In the present study, we investigate what tandem leaders and follo... Read More about Ant search strategies after interrupted tandem runs.

Record dynamics in ants (2010)
Journal Article

The success of social animals (including ourselves) can be attributed to efficiencies that arise from a division of labour. Many animal societies have a communal nest which certain individuals must leave to perform external tasks, for example foragin... Read More about Record dynamics in ants.

Emergency networking: famine relief in ant colonies (2010)
Journal Article

Resource distribution is fundamental to social organization, but it poses a dilemma. How to facilitate the spread of useful resources but restrict harmful substances? This dilemma reaches a zenith in famine relief. Survival depends on distributing fo... Read More about Emergency networking: famine relief in ant colonies.

Division of labour in ant colonies in terms of attractive fields (2009)
Journal Article

In nature there exist many mechanisms giving rise to self-regulation. One such mechanism is the division of labour in insect societies. Within this work we propose a mathematical model for the allocation of tasks in ant colonies, where each of the ta...

Symbionts of societies that fission: Mites as guests or parasites of army ants (2009)
Journal Article

Recently, Hughes et al. (Trends in Ecology & Evolution, 23, 672-677, 2008) have theorised that symbionts of large, long-lived, homeostatic, and well defended social insect colonies should mostly be of low virulence. If the symbionts are rare, i.e. fe... Read More about Symbionts of societies that fission: Mites as guests or parasites of army ants.

Objective evidence for the use of polylactic acid implants in HIV-associated facial lipoatrophy using three-dimensional surface laser scanning and psychological assessment (2009)
Journal Article

The advent of highly active antiretroviral therapy (HAART) has dramatically improved the life expectancy of people infected with human immunodeficiency virus (HIV). Although patients often have excellent disease control with these combinations of ant...

A randomized clinical trial of a brief hypnosis intervention to control venepuncture-related pain of paediatric cancer patients (2009)

Venepuncture for blood sampling can be a distressing experience for a considerable number of children. A prospective controlled trial was conducted to compare the efficacy of a local anaesthetic (EMLA) with a combination of EMLA with self-hypnosis in...

Radio tagging reveals the roles of corpulence, experience and social information in ant decision making (2009)
Journal Article

Ant colonies are factories within fortresses (Oster and Wilson 1978). They run on resources foraged from an outside world fraught with danger. On what basis do individual ants decide to leave the safety of the nest? We investigated the relative roles...

The behaviour of ant transporters at the old and new nests during successive colony emigrations (2008)
Journal Article

Colonies of the ant Temnothorax albipennis improve their collective performance over successive emigrations (Langridge et al. Behav Ecol Sociobiol 56:523-529, 2004, Behav Ecol Sociobiol 62:447-456, 2008). Here, by analysing the performance of individ...

Can ant colonies choose a far-and-away better nest over an in-the-way poor one? (2008)
Journal Article

Nest choice in the ant Temnothorax albipennis is a model system for investigating collective decision making. Previous research has demonstrated the sophistication of this decentralized system, yet such studies have focused on binary choices in which...
